Web Inspector: Give nested inspectors their own process pool

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

* SUMMARY
Give nested inspectors their own process pool.

When inspecting the inspector, in order for profiling information to be useful the inspector¹ and inspector² should be in separate processes (or at least not share the same VM). When sampling I was seeing JavaScript running in both inspectors in the sample, because they were sharing the same process and VM.

We could create a Vector for pools per level, but I think just 2 pools is fine for now.

Needs a WK2 Owner nod.

I think this needs to be a reference or a ** to make the later assignment work right. As it stands, I suspect this makes a new pool each time and s_mainInspectorProcessPool / s_nestedInspectorProcessPool are always null.
